i also believe that tie-fighters are designed for smaller people. I remember reading that Vader has a special one designed so he could fit in it.
He did. That doesn't mean that they're for smaller people though just that Darth Vader was really that huge with that stupid armor.
not a special one designed JUST for FITTING purposes! his is one with hyperspace, torps and deflector shields UNLIKE regular tie-fighters. get the specs, people.
